Soap dispenser



Patented June 3 0, 1953 UNITED STATES PATENT OFFICE SOAP DISPENSER Hugh H. Logan, Ila Canada, oalis ,1 Application January 17, 1949," Serial n 71,295

This invention relates generally to hoods or cas n s for liquid soap dispensers, and the object o f t;he invention is the provision of a novel and improved hood for a plunger type liquid soap dispenser, provided with formations guarding the dispenser against vandalism.

Particularly for institutional use, such as State asylums and prisons, but also in certain schools, and in places open to the public generally, plumbing fixtures are subject to theft, mutilation, and general vandalism. It is a common occurrence, for instance, for a towel tied into a loopto be slung around a soap dispenser, and used as a sling by which the dispenser may be bent and broken from the wall. For instance, the foot of the person may be placed inside the sling, and enough leverage or weight so exerted to pry the fixture from the wall. The present invention deals with the provision of a liquid soap dispenser fixture having a casing or hood so formed as to defy the usual attempts to bend or break it from its mounting.

A preferred embodiment of the invention appears in the drawings, to which reference will be made in the course of the ensuing detailed description. In the drawings:

Figure 1 is a perspective view of a liquid soap dispenser and casing in accordance with the invention;

Figure 2 is a front elevational view thereof;

Figure 3 is a longitudinal section on line 33 of Figure 2; and

Figure 4 is a section on line 44 of Figure 3.

In the drawings, numeral I designates generally a horizontally disposed barrel, within which is slidably fitted the conventional reciprocating plunger I l urged to its advance position by spring 12, and movable a limited distance in the reverse direction, against said spring, by pressure against thumb piece i3 formed on the outer end of the plunger. It will be understood that the plunger and associated soap feeding mechanism are entirely conventional, and that the details of structure need not be described herein, beyond to note that barrel I9 is internally screwthreaded at its rearward end, as at I 4, for engagement with a liquid soap supply pipe (not shown) and that the plunger is longitudinally bored at 15 for passage of the liquid soap, and furnished with a downwardly discharging outlet ll leading from 3 Claims. (01. Isa-3823 said bore l6 through the bottom of thumb piece A check valve at 18, provided with a spring [9, controls the inlet to the feeding mechanism, and closes and opens respectively, as plunger I l is alternately depressed, and permitted to return to its forward position. The invention, however, is entirely in the casing, and not in the, soap feed ing' mechanism, and-further description of the latter is unnecessary.

Formed integrally with the bottom of barrel l0, and extending horizontally in both directions therefrom is a horizontal bottom wall Zil, which extends the full length of the cylindrical extent of the barrel, and merges at the edges with the bottom edges of vertical side walls 2!. Said side walls merge at the top with a top wall 22 which is arch-shaped in contour, and downwardly inclined at a substantial angle, preferably as illustrated, from the rearward end of the casing toward its forward end or nose portion 2a. The latter is preferably approximately coplanar with the end of plunger finger-piece i3 when the latter is in its outermost position (Figure 3), and there is a short conical inwardly converging wall 25 joining nose 24 with the forward end of barrel Ill. The entire nose 24 is arch-shaped, and the connecting wall 25 is therefore an incomplete cone, the forward end portion of the cylindrical extent of the barrel Ill being therefore exposed at the bottom, as appears at 27 in the drawings. Engagement of nozzle ll with this end or shoulder 2'! serves as a means limiting inward movement of plunger I I.

It will be seen that there is only a small or narrow annular space 29 between thumb piece E 3 and the wall 25, insufficient for a towel slin or the like to be inserted and a purchase thereby gained against the exposed end portion of the plunger. It will further be seen that a towel sling or the like engaged over inclined top 22 will slide off if any weight is imposed. In fact, the casing of the invention successfully defies the usual types of effort made to break the article from the wall.

The casing is completed by a wall plate or flange 35 formed integrally with the side, top and bottom walls aforesaid, said plate being formed with holes for screws which maybe engaged with threaded sockets in a sub-mounting plate 36 screwed to the wall as by wood screws 3?.

I claim:

l. A casing for a liquid soap dispenser, comprising: a horizontally disposed plunger-receiving barrel having means at its rearward end for connection with a supply pipe, a hood of generally arch-shaped cross section over said barrel and projecting forwardly therefrom, said hood having a substantially arch-shaped front end wall, a top wall which slopes upwardly at a substantial angle to horizontal from said forward end wall to the rearward end of the hood, and having also side walls on opposite sides of and spaced horizontally from said barrel, a bottom wall joining the lower edges of said side walls with the bottom of said barrel, and a diverging wall connecting the top and side portions of the front end of said barrel with said arch-shaped end wall of said hood, the lower portion of the front end of said barrel remaining exposed.

2. A casing for a liquid soap dispenser, comprising: a horizontally disposed plunger-receiving barrel having means at its rearward end for connection with a supply pipe, a hood of generally arch-shaped cross section over said barrel and projecting forwardly therefrom, said hood having a substantially arch-shaped front end wall, a top wall which slopes upwardly at a substantial angle to horizontal from said forward end wall to the rearward end of the hood, and having also side walls on opposite sides of and spaced 20 horizontally from said barrel, and a bottom wall joining the lower edges of said side walls with said harreL- 3. A casing for a liquid soap dispenser, comprising: a horizontally disposed plunger-receiving barrel having means at its rearward end for connection with a supply pipe, a hood having upper and side walls over and around the sides of said barrel, said side walls joined to the forward end portion of the barrel and to the bottom of said barrel, a vertical wall flange integral with the rearward end of said upper and side walls of said hood, said upper wall sloping upwardly from the'forward end of the hood substantially to the juncture of said upper wall with said wall flange at a substantial angle of inclination from horizontal.
